RESUMEN

There has been increasing recognition of gender-based inequity as a barrier to successful policy implementation. This consensus, coupled with an increasing frequency of emergencies in human and animal populations, including infectious disease events, has prompted policy makers to re-evaluate gender-sensitivity in emergency management planning. Seeking to identify key publications relating to gendered impacts and considerations across diverse stakeholders in different types of animal health emergencies, we conducted a non-exhaustive, targeted scoping review. We developed a matrix for both academic and policy literature that separated animal health emergencies into two major categories: humanitarian crises and infectious disease events. We then conducted semi-structured interviews with key animal health experts. We found minimal evidence of explicit gender responsive planning in animal health emergencies, whether humanitarian or infectious disease events. This was particularly salient in Global North literature and policy planning documents. Although there are some references to gender in policy documents pertaining to endemic outbreaks of African swine fever (ASF) in Uganda, most research remains gender blind. Despite this, implicit gendered themes emerged from the literature review and interviews as being direct or indirect considerations of some research, policy, and implementation efforts: representation; gendered exposure risks; economic impact; and unpaid care. Absent from both the literature and our conversations with experts were considerations of mental health, gender-based violence, and intersectional impacts. To remedy the gaps in gender-based considerations, we argue that the intentional inclusion of a gender transformative lens in animal health emergency planning is essential. This can be done in the following ways: (1) collection of disaggregated data (race, gender, sexual orientation, etc.); (2) inclusion of gender experts; and (3) inclusion of primary gendered impacts (minimal representation of women in policy positions, gender roles, economic and nutrition impacts) and secondary gendered impacts (gender-based violence, mental health, additional unpaid care responsibilities) in future planning.

RESUMEN

Global and national authorities have not historically approached animal health emergencies through a gendered lens. Yet these events almost certainly have gendered dimensions, such as differential engagement of women or men depending on their culturally accepted or assigned roles for animal care; risk of exposure to zoonoses; and access to emergency resources during response and recovery. Despite the role that gender seems to play with respect to animal health emergencies, little research has been conducted to better understand such dynamics, and little policy has been promulgated to address it in a way that optimizes response while ensuring equitable outcomes. This piece summarizes 3 key themes that emerged from a panel discussion on gender and animal health emergencies at the World Organisation for Animal Health Global Conference on Emergency Management in April 2023. These themes were differential gendered exposure to pathogens; a lack of equitable gender representation in animal health decision-making; and enhancement of pathways for recognizing gender in national and international actions in preparing for, detecting, and responding to animal health emergencies. Beyond increasing opportunities for women to engage in leadership, the animal health and veterinary communities will benefit from connecting practitioners with gender experts to develop more integrative approaches to emergency preparedness and management. Animal health professionals should also advocate for further research to elucidate gender-specific dynamics in human populations in the context of animal emergencies and the promulgation of evidence-based policies. Such transformative efforts will lead to better outcomes for all people who depend on and provide care for animals.

RESUMEN

Behavioral variant frontotemporal dementia is characterized by heterogeneous frontal, insular, and anterior temporal atrophy patterns that vary along left-right and dorso-ventral axes. Little is known about how these structural imbalances impact clinical symptomatology. The goal of this study was to assess the frequency of frontotemporal asymmetry (right- or left-lateralization) and dorsality (ventral or dorsal predominance of atrophy) and to investigate their clinical correlates. Neuropsychiatric symptoms and structural images were analyzed for 250 patients with behavioral variant frontotemporal dementia. Frontotemporal atrophy was most often symmetric while left-lateralized (9%) and right-lateralized (17%) atrophy were present in a minority of patients. Atrophy was more often ventral (32%) than dorsal (3%) predominant. Patients with right-lateralized atrophy were characterized by higher severity of abnormal eating behavior and hallucinations compared to those with left-lateralized atrophy. Subsequent analyses clarified that eating behavior was associated with right atrophy to a greater extent than a lack of left atrophy, and hallucinations were driven mainly by right atrophy. Dorsality analyses showed that anxiety, euphoria, and disinhibition correlated with ventral-predominant atrophy. Agitation, irritability, and depression showed greater severity with a lack of regional atrophy, including in dorsal regions. Aberrant motor behavior and apathy were not explained by asymmetry or dorsality. This study provides additional insight into how anatomical heterogeneity influences the clinical presentation of patients with behavioral variant frontotemporal dementia. Behavioral symptoms can be associated not only with the presence or absence of focal atrophy, but also with right/left or dorsal/ventral imbalance of gray matter volume.

RESUMEN

Patients with neurodegenerative disorders experience a range of neuropsychiatric symptoms. The neural correlates have been explored for many individual symptoms, such as apathy and disinhibition. Atrophy patterns have also been associated with broadly recognized syndromes that bring together multiple symptoms, such as the behavioural variant of frontotemporal dementia. There is substantial heterogeneity of symptoms, with partial overlap of behaviour and affected neuroanatomy across and within dementia subtypes. It is not well established if there are anatomically distinct behavioural subphenotypes in neurodegenerative disease. The objective of this study was to identify shared behavioural profiles in frontotemporal dementia-spectrum and Alzheimer's disease-related syndromes. Additionally, we sought to determine the underlying neural correlates of these symptom clusters. Two hundred and eighty-one patients diagnosed with one of seven different dementia syndromes, in addition to healthy controls and individuals with mild cognitive impairment, completed a 109-item assessment capturing the severity of a range of clinical behaviours. A principal component analysis captured distinct clusters of related behaviours. Voxel-based morphometry analyses were used to identify regions of volume loss associated with each component. Seven components were identified and interpreted as capturing the following behaviours: Component 1-emotional bluntness, 2-emotional lability and disinhibition, 3-neuroticism, 4-rigidity and impatience, 5-indiscriminate consumption, 6-psychosis and 7-Geschwind syndrome-related behaviours. Correlations with structural brain volume revealed distinct neuroanatomical patterns associated with each component, including after controlling for diagnosis, suggesting that localized neurodegeneration can lead to the development of behavioural symptom clusters across various dementia syndromes.

RESUMEN

Purpose: Semaglutide has demonstrated safe and effective weight loss for overweight and obesity, including participants with concomitant type 2 diabetes mellitus (T2DM), in randomized placebo-controlled trials (RCTs). We conducted a systematic literature review (SLR) and network meta-analyses (NMA) to compare weekly semaglutide 2.4 mg with pharmacological comparators for weight management in overweight or obesity. Methods: The SLR was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) checklist. NMAs were performed to compare weight change for semaglutide 2.4 mg with comparators using data identified in the SLR. The populations of interest were total population, normal glucose tolerance, non-T2DM, pre-diabetes, and T2DM. Included outcomes were weight change from baseline (CFB, %) at 52 weeks and proportion of participants losing ≥5% baseline fasting body weight at 12 weeks (at full therapeutic dose). Results: The SLR identified 108 RCTs examining non-surgical interventions, of which 41 were considered for inclusion in the NMAs. In all populations, semaglutide 2.4 mg was associated with a greater percentage weight CFB with 52 weeks of treatment versus all available comparators. In all populations, semaglutide was associated with a higher likelihood of participants losing ≥5% of baseline fasting body weight at 12 weeks versus all available comparators. Conclusion: In NMA, semaglutide 2.4 mg demonstrated effective weight loss (≥5%) in the total population and all subpopulations of glucose tolerance versus active comparators. Semaglutide is an effective treatment that may address unmet need in the management of overweight and obesity.

RESUMEN

BACKGROUND: The COVID-19 pandemic has necessitated rapid development of preparedness and response plans to quell transmission and prevent illness across the world. Increasingly, there is an appreciation of the need to consider equity issues in the development and implementation of these plans, not least with respect to gender, given the demonstrated differences in the impacts both of the disease and of control measures on men, women, and non-binary individuals. Humanitarian crises, and particularly those resulting from conflict or violence, exacerbate pre-existing gender inequality and discrimination. To this end, there is a particularly urgent need to assess the extent to which COVID-19 response plans, as developed for conflict-affected states and forcibly displaced populations, are gender responsive. METHODS: Using a multi-step selection process, we identified and analyzed 30 plans from states affected by conflict and those hosting forcibly displaced refugees and utilized an adapted version of the World Health Organization's Gender Responsive Assessment Scale (WHO-GRAS) to determine whether existing COVID-19 response plans were gender-negative, gender-blind, gender-sensitive, or gender-transformative. RESULTS: We find that although few plans were gender-blind and none were gender-negative, no plans were gender-transformative. Most gender-sensitive plans only discuss issues specifically related to women (such as gender-based violence and reproductive health) rather than mainstream gender considerations throughout all sectors of policy planning. CONCLUSIONS: Despite overwhelming evidence about the importance of intentionally embedding gender considerations into the COVID-19 planning and response, none of the plans reviewed in this study were classified as 'gender transformative.' We use these results to make specific recommendations for how infectious disease control efforts, for COVID-19 and beyond, can better integrate gender considerations in humanitarian settings, and particularly those affected by violence or conflict.

RESUMEN

BACKGROUND: In the emergency department (ED), residents and attendings may have a short-term relationship, such as a single shift. This poses challenges to learner assessment, instructional strategy selection, and provision of substantive feedback. We implemented a process for residents to identify goals for ED shifts; characterized residents' goals; and determined how goal identification affected learning, teaching, and feedback. METHODS: This was an observational study in a large, tertiary pediatric ED using mixed methods. Residents were asked to identify learning goals for each shift and were asked postshift if they had identified, accomplished, and/or received feedback on these goals. Goals were categorized by Accreditation Council for Graduate Medical Education Core Competencies. Predictors of goal identification, accomplishment, and receipt of feedback were determined. Residents and attendings were interviewed about their experiences. RESULTS: We collected 306 end-of-shift surveys (74% response rate) and 358 goals and conducted 29 interviews. We found that: 1) Goal setting facilitated perceived learning. Residents identified goals 54% of the time. They accomplished 89% of and received feedback on 76% of goals. 2) Residents' perceived weaknesses, future practice settings, and available patients informed their goals. Most goals mapped to patient care (59%) or medical knowledge (37%) competencies. 3) Goal identification helped attendings determine residents' needs. 4) Ideal goals were specific and achievable. 5) Common barriers were busyness of the ED and difficulty creating goals. Residents were less likely to identify goals (odds ratio [OR] = 0.62, 95% confidence interval [CI] = 0.41 to 0.94) and receive feedback on busy evening shifts (OR = 0.19, 95% CI = 0.10 to 0.37) and were most likely to receive feedback overnight (OR = 3.66, 95% CI = 1.87 to 7.14). CONCLUSIONS: Asking residents to identify goals for ED shifts as an instructional strategy facilitated perceived learning, goal accomplishment, and receipt of feedback. Resident-driven goal identification is a simple and effective instructional strategy that physicians can incorporate into their precepting in the ED.

RESUMEN

Science and Engineering (S&E) fairs are a valuable educational activity and are believed to increase students' engagement and learning in science and engineering. However, due to differences in resources, many schools do not implement fairs to achieve these benefits for their students. This study reports the findings of a program intended to increase the participation of students from low-achieving and under-resourced schools in a regional fair program that feeds into the international fair competition. We found that the number of schools and projects participating in our regional fair increased dramatically since the start of the program. Teachers had mostly positive expectations for the project and expressed buy-in for the effort the project would take. They recruited a diverse pool of students to participate in the school fairs. Quasi-experimental methods allowed us to explore the impact of completing S&E fairs on student gains on science self-efficacy, interest and value perceptions. Controlling for pre-existing differences in these attitudes, we found that students not completing projects showed declines in their science attitudes during the year. Students who completed projects maintained similar attitudes, while those whose projects advanced to the regional fair had substantial gains on all three variables. It is unknown whether this gain can be attributed to the experience of engaging with a quality project, from being the kind of student who completes a quality project, or some other factor. Future research with greater experimental control could address these questions.

RESUMEN

A new naphthylsalophen and its 3 : 2 ligand-to-lanthanide sandwich-type complexes were isolated. When excited at 380 nm, the complexes display the characteristic metal-centred emission for NdIII, ErIII and YbIII. Upon 980 nm excitation, in mixed lanthanide and the Er complexes, Er-centred upconversion emission at 543 and 656 nm is observed, with power densities as low as 2.18 W cm-2.

RESUMEN

Naturally occurring mutations in two separate genes, PKD1 and PKD2, are responsible for the vast majority of all cases of autosomal dominant polycystic kidney disease (ADPKD), one of the most common genetic diseases affecting 1 in 1000 Americans. The hallmark of ADPKD is the development of epithelial cysts in the kidney, liver, and pancreas. PKD1 encodes a large plasma membrane protein (PKD1, PC1, or Polycystin-1) with a long extracellular domain and has been speculated to function as an atypical G protein coupled receptor. PKD2 encodes an ion channel of the Transient Receptor Potential superfamily (TRPP2, PKD2, PC2, or Polycystin-2). Despite the identification of these genes more than 20 years ago, the molecular function of their encoded proteins and the mechanism(s) by which mutations in PKD1 and PKD2 cause ADPKD remain elusive. Genetic, biochemical, and functional evidence suggests they form a multiprotein complex present in multiple locations in the cell, including the plasma membrane, endoplasmic reticulum, and the primary cilium. Over the years, numerous interacting proteins have been identified using directed and unbiased approaches, and shown to modulate function, cellular localization, and protein stability and turnover of Polycystins. Delineation of the molecular composition of the Polycystin complex can have a significant impact on understanding their cellular function in health and disease states and on the identification of more specific and effective therapeutic targets.

RESUMEN

Children represent one of the most vulnerable parts of the population regarding the effects of pollutants exposure on health. In this study, hair samples were collected between October 2013 and August 2015 from 142 French children originating from different geographical areas (urban and rural) and analysed with a GC/MS-MS method, allowing for the detection of 55 biomarkers for pesticides and metabolites both persistent and non-persistent from different families, including: organochlorines, organophosphates, pyrethroids, azoles, dinitroanilines, oxadiazines, phenylpyrazoles and carboxamidas; 4 polychlorobiphenyls (PCBs) and 5 polybromodiphenylethers (PBDEs). The number of compounds detected in each sample ranged from 9 up to 37 (21 on average), which clearly highlighted the cumulative exposure of the children. The results also showed a wide range of concentration of the pollutants in hair (often more than 100 times higher in the most exposed child compared to the less exposed), suggesting significant disparities in the exposure level, even in children living in the same area. In addition to the detection of currently used chemicals, the presence of persistent organic pollutants (POPs) in children also suggests that the French population is still exposed to POPs nowadays. PCP, DEP, PNP, 3Me4NP, trans-Cl2CA, 3PBA, fipronil and fipronil sulfone, presented statistically significant higher concentration in the hair of boys compared to girls. PCP, PNP and 3Me4NP presented statistically significant higher concentration in younger children. Finally, this study also suggests that local environmental contamination would not be the main source of exposure, and that individual specificities (habits, diet…) would be the main contributors to the exposure to the pollutants analysed here. The present study strongly supports the relevance of hair for the biomonitoring of exposure and provides the first values of organic pollutant concentration in the hair of French children.

RESUMEN

Here, we present the atomic resolution crystallographic structure, the function, and the ion-binding properties of the KcsA mutants, G77A and G77C, that stabilize the 2,4-ion-bound configuration (i.e., water, K+, water, K+-ion-bound configuration) of the K+ channel's selectivity filter. A full functional and thermodynamic characterization of the G77A mutant revealed wild-type-like ion selectivity and apparent K+-binding affinity, in addition to showing a lack of C-type inactivation gating and a marked reduction in its single-channel conductance. These structures validate, from a structural point of view, the notion that 2 isoenergetic ion-bound configurations coexist within a K+ channel's selectivity filter, which fully agrees with the water-K+-ion-coupled transport detected by streaming potential measurements.

RESUMEN

An in silico model for the 1:1 ferredoxin (Fd)/nitrate reductase (NR) complex, using the known structure of Synechocystis sp. PCC 6803 Fd and the in silico model of Synechococcus sp. PCC 7942 NR, is used to map the interaction sites that define the interface between Fd and NR. To test the electrostatic interactions predicted by the model complex, five positively charged NR amino acids (Arg43, Arg46, Arg197, Lys201, and Lys614) and a negatively charged amino acid (Glu219) were altered using site-directed mutagenesis and characterized by activity measurements, metal analysis, and electron paramagnetic resonance (EPR) studies. All of the charge replacement variants retained wild-type levels of activity with reduced methyl viologen (MV), but a significant decrease in activity was observed for the R43Q, R46Q, K201Q, and K614Q variants when reduced Fd served as the electron donor. EPR analysis as well as the Fe and Mo analyses showed that loss of activity observed with these variants was not the consequence of perturbation of the Mo center or [4Fe-4S] cluster. Therefore, the loss of the Fd-linked specific activity observed with these variants can be explained only by invoking a role for Arg43, Arg46, Lys201, and Lys614 in Fd binding. The R43Q, R46Q, K201Q, and K614Q NR variants also showed a decreased binding affinity for Fd, compared to that of wild-type NR, supporting a key role of these four positively charged residues in the productive binding of Fd.

RESUMEN

BACKGROUND: Measuring outcomes of emergency care is of key importance, but current metrics, such as 72-hour return visit rates, are subject to ascertainment bias, incentivize overtesting and overtreatment at initial visit, and do not reflect the full burden of disease and morbidity experienced at home following ED care. There is increasing emphasis on including patient-reported outcomes, but the existing patient-reported measures have limited applicability to emergency care. OBJECTIVE: The objective was to identify concepts for inclusion in a patient-reported outcome measure for ED care and assess differences in potential concepts by health literacy. METHODS: A three-phase qualitative study was completed using freelisting and semistructured interviewing for concept identification, member checking for concept ranking, and cognitive interviewing for question development. Participants were drawn from three tertiary care EDs. Parents of patients (pediatric) or patients (adult) with asthma completed a demographic survey and an assessment of health literacy. Phase 1 participants also completed a freelisting exercise and qualitative interview regarding the definition of success following ED discharge. Phase 2 participants completed a member checking survey based on concepts identified in Phase 1. Phase 3 was a pilot of trial questions based on the highest-ranked concepts from Phase 2. RESULTS: Phase 1 enrolled 22 adult patients and 37 parents of pediatric patients. Phase 2 enrolled 41 adult patients and 200 parents. Phase 3 involved 15 parents. Across all demographic/literacy groups, Phase 1 participants reported return to usual activity and lack of asthma symptoms as the most important markers of success. In Phase 2, symptom improvement, medication use and access, and asthma knowledge were identified as the most important components of the definition of post-ED discharge success. Phase 3 resulted in five questions for the proposed measure. CONCLUSIONS: A stepwise qualitative process can identify, rank, and formulate questions based on patient-identified concepts for inclusion in a patient-reported outcome measure for ED discharge. The four key concepts identified for inclusion: symptom improvement, medication access, correct medication use, and asthma knowledge are not measured by existing quality metrics.

RESUMEN

Prenatal stress has been linked to deficits in neurological function including deficient social behavior, alterations in learning and memory, impaired stress regulation, and susceptibility to adult disease. In addition, prenatal environment is known to alter cardiovascular health; however, limited information is available regarding the cerebrovascular consequences of prenatal stress exposure. Vascular disturbances late in life may lead to cerebral hypoperfusion which is linked to a variety of neurodegenerative and psychiatric diseases. The known impact of cerebrovascular compromise on neuronal function and behavior highlights the importance of characterizing the impact of stress on not just neurons and glia, but also cerebrovasculature. Von Willebrand factor has previously been shown to be impacted by prenatal stress and is predictive of cerebrovascular health. Here we assess the impact of prenatal stress on von Willebrand factor and related angiogenic factors. Furthermore, we assess the potential protective effects of concurrent anti-depressant treatment during in utero stress exposure on the assessed cerebrovascular endpoints. Prenatal stress augmented expression of von Willebrand factor which was prevented by concurrent in utero escitalopram treatment. The functional implications of this increase in von Willebrand factor remain elusive, but the presented data demonstrate that although prenatal stress did not independently impact total vascularization, exposure to chronic stress in adulthood decreased blood vessel length. In addition, the current study demonstrates that production of reactive oxygen species in the hippocampus is decreased by prenatal exposure to escitalopram. Collectively, these findings demonstrate that the prenatal experience can cause complex changes in adult cerebral vascular structure and function.

RESUMEN

OBJECTIVES: Emergency department (ED) discharge requires conveying critical information in a time-limited and distracting setting. Limited health literacy may put patients at risk of incomplete comprehension, but the relationship between discharge communication needs and health literacy has not been well defined. The goal of this study was to characterize the variation in needs and preferences regarding the ED discharge process by health literacy and identify novel ideas for process improvement from parents and patients. METHODS: This was an in-depth qualitative interview study in two EDs using asthma as a model system for health communication. Adult patients and parents of pediatric patients with an asthma exacerbation and planned discharge were enrolled using purposive sampling to balance across literacy groups at each site. Interviews were audiotaped, transcribed, coded independently by two team members, and analyzed using a modified grounded theory approach. Interviews were conducted until thematic saturation was reached in both literacy groups at each site. RESULTS: In-depth interviews were completed with 51 participants: 20 adult patients and 31 pediatric parents. The majority of participants identified barriers related to ED providers, such as use of medical terminology, and systems of care, such as absence of protected time for discharge communication. Patients with limited health literacy, but not those with adequate literacy, identified conflicting information between health care sources as a barrier to successful ED discharge. CONCLUSIONS: Participants across literacy groups and settings identified multiple actionable areas for improvement in the ED discharge process. These included the use of simplified/lay language, increased visual learning and demonstration, and the desire for complete information. Individuals with limited literacy may particularly benefit from increased attention to consistency.

RESUMEN

OBJECTIVE: Teach-back may improve communication, but has not been well studied in the emergency setting. The goal of this study was to characterize perceptions of teach-back in the emergency department (ED) by health literacy. METHODS: We conducted an in-depth interview study on the ED discharge process examining teach-back techniques in two tertiary care centers (adult and pediatric), using asthma as a model system for health communication. Participants were screened for health literacy, and purposive sampling was used to balance the sample between literacy groups. Interviews were conducted until thematic saturation was reached for each literacy group at each site; audiotaped, transcribed, coded, and analyzed using a modified grounded theory approach. RESULTS: Fifty-one interviews were completed (31 parents; 20 patients). Across all groups, participants felt that teach-back would help them confirm learning, avoid forgetting key information, and improve doctor-patient communication. Participants with limited health literacy raised concerns about teach-back being condescending, but suggested techniques for introducing the technique to avoid this perception. CONCLUSION: Most participants were supportive of teach-back techniques, but many were concerned about perceived judgment from providers.
